SPECIFICATION forming part of Letters Patent No. 441,739, dated December'2, 1890.

Application filed August 4, 1890.

To all whom t may concern.:

Be it known that I, CHARLES WILLIAM BLAKE, a citizen of the United States, residing at Charleston, in the county of Charleston and State of South Carolina, have invented a new and useful Cut-OE, of which the following' is a specication.-

This invention relates to water-distribution, and more especially to the cut-offs and t spouts employed therein; and the object of the same is to provide improvements in devices of this character. This object I accomplish by the mechanism hereinafter more fully described, and the points of novelty whereof are particularly pointed out in the claims.

In the drawings, Figure l is a section through this device with the parts thereof in their normal position. Fig-2 is a similarsection with the parts in the opposite position. Fig. 3 is a detail in perspective of the iioat and its guide. Fig. 4t is a detail in perspective ofv the iioat-tank-supplying device. Fig. y Fig. 6 is a perspective detail of the switch. Fig. 7 is a side elevation, partly in perspective, showing the manner in which access is had to the interior of this device.

Referringvto the said drawings, the letter C designates a casing, adjacent to which is a float-tank T, separated from the casing by a high partition P, and provided with an overiiow O, located at a point above the usual level of the water, as shown. Mounted upon the cover of the casing is an inlet-pipe I, which passes horizontally along above the casing, then down thereinto, and opens within a switch S, which is of funnel shape, pivoted at p between the sides of the casing. When this switch is in the position shown in Fig. l the water which may flow through the inletpipe I will be directed into the waste; but when the switch is turned to the position shown in Fig. 2 the water will be directed into the cistern. The following are the means employed for automaticallymovingthe switch after the water has flowed for a sufficient time over the roof to cleanse the same, which moving of the switch directs the water from the clean roof into the cistern.

Within the tank T is a vertical rod V, upon which slides a tube t, and on this tube is mounted a fioat F, preferably having a conical upper end, as shown. Near the upper end of the tube are twoenlargements E, and extending from the switch S is a loop-shaped handle H, which embraces the tube between said enlargements. By this means when water is admitted to the tank T and the float rises, the handle I-I will be raised and will 6o cause the switch S to move in a manner which will be clearly understood. As the water falls within the tank T the switch will be returned to its normal position, and the lower endof the tube will finally reach and rest upon the supporting cross-piece c at the lower end of the guide-rod V, whereby the iioat will be sustained above the level of whatever Water may remain in the tankand will be thereby prevented from rusting. Fol- 7o lowing is a description of the devices which I employ for filling the tank to raisesaid float.

Arranged below the inlet-pi pe I is aboX B, as best seen in Fig. 4, and at opposite sides of this box are inlet-openings z', preferably covered with wire-cloth, and so arranged that a light flow of water might pass through the pipe I, along the bottom thereof, without iiow-` ing into the openings; but as soon as a good- 8o sized stream passes through the inlet-pipe a certain portion will enter the box through the openings 'L'. In this way what water may run from the roof as the result ot' a'heavy dew or of a very light precipitation would pass between the openings i' without getting into -the box B. When, however, an ordinaryV rain occurs and the water iiows from the eaves into and through the pipe I, it will be directed for a considerable time into the 9o waste, and meanwhile a small quantity will be passing through the openings t into the box B, down the pipe D, through the regulating-valve r into the tank, and will rise in the latter until the float is operated and the 95 switch is moved, as above described. Said regulating-valve 7' is an ordinary stop-cock, whose handle moves between stops s, (see Fig 5,) whereby it cannot be completely closed, and a scale A is preferably marked upon the end of the tank, in order that the cock may be set as desired.

In order that the How of water through the inlet-openings /L' and into the tank may cease after the float has been raised, whereby all the water then iiowing through the pipe I will be directed into the cistern, the following devices are provided: G is a rod having a flat plate f at its lower end adapted to close the lower end of the stop-cock r, and from this plate the rod G extends upwardly through guiding-eyes g on the cock and has a bent upper end G', which stands in the path of the handle II of the switch. As the iioat rises and carries said handle with it, the latter strikes the end G', raises the rod G, and brings the fiat plate f against the lower end of the cock 7', and thus cuts off all tlowof waterinto the tank. As soon as any of the. water-in the tank is withdrawn and the float F descends a trifie the plate j' opens communication between the openings and the interior of the tank, and if water be still iiowing through the pipe I it will be directed into the tank.

After the rain is over it is desirable that the switch S be returned to the position shown in Fig. l, and some means must be provided for emptying the tank T. Across the lower end of the latter I put two screens N, between whieh is a filling of pebbles or gravel n, and to the lower end of the tank is atm tached rst a filter M, containing asbestus or other suitable material, and then an outletcock Z, moving between stops s and over a scale, the same as the handle of the regulating-cock o'. By this means the water in the tank is first cleansed from sediment and impurities, then passed through the filter M, and finally drawn off through the cock Z, whence it may be directed into the cistern, if desired.

The sides of the casing C are preferably provided with hinged doors cl, whereby access may be had thereto, as for cleaning and repair. The entire casing maybe supported by ears c, through which nails or screws are passed into the wall of a building or other inlet and exhaustV pipes connected with said tank, a switch S, and a' handle H thereon, of the float F, having a tubular stem t sliding upon said vertical rod and passing loosely through said handle, and enlargements E upon said stem above and below the handle, as set forth.

3.
